  PURPOSE:Under a noisy "cocktail-party" condition with multiple-people talking,listeners often ask the talker to repeat the attended sentence for their better recognition.

目的:给双眼呈现不同的刺激或者双稳态刺激会导致视觉意识的切换。间歇性呈现的方式会使双稳态刺激稳定在一个知觉上,可能是由知觉记忆导致的。本文拟通过研究皮层距离对双稳态知觉稳定性的影响,探讨这种知觉记忆是否存储在早期有视网膜分区的视皮层,或者更晚的脑区。方法:间歇性呈现双眼竞争和双稳态刺激,当空间距离保持不变的情况下,改变刺激在早期视觉皮层上表征的皮层距离,研究早期视皮层距离的变化对知觉稳定性的影响。
PURPOSE:Ambiguous stimulations can induce involuntary alternation between exclusive subjective perceptions.Numerous studies have demonstrated that a number of brain regions was involved in bistable pe
目的:视知觉利用影像信息和光流信息。清晰影像中的高频空间信号使观察者感知细节、识别场景。模糊影像中高频信号缺失,静止的观察者无法识别场景。本文探究观察者运动产生的光流能否标示空间关系,弥补模糊影像,促进场景识别。方法:摄像机在8个静态场景中运动并拍下视频,每段视频选20帧图模糊处理。被试依次从不同材料中识别场景:(1)单帧图片;(2)全部20帧图片,无运动信息;(3)连续呈现图片,有运动信息;(4
PURPOSE:In a horizontal pattern consisting of zigzagging strips of phase-shifted abutting line gratings,strong diagonal and lateral illusory motion is perceived when the pattern is moved up or down at
目的: 经颅电刺激(Transcranial Electrical Stimulation,TES)是非侵入性的脑刺激方法,包括经颅直流电刺激(tDCS)和经颅交流电刺激(tACS)等。先前的研究认为经颅电刺激能改变大脑皮层的兴奋性,有效调控被试的视觉功能。本研究探讨单次的经颅电刺激对视觉基本功能的影响。
PURPOSE:Visual environment changes at multiple timescales.It is thus hypothesized that adaptation mechanisms operate at differing timescales to accommodate the environmental changes.
METHODS:Seventeen amblyopic subjects and twenty control subjects were recruited to undergo a resting-state functional magnetic resonance imaging scan.

PURPOSE:Figure-ground segmentation is a fundamental task for biological and artificial visual systems.The visual figure is many multiples greater in size than the receptive fields/filters of early vis
PURPOSE:Human subjects are more sensitive to luminance decrements than luminance increments,as is evident by a lower threshold and shorter latency for dark stimuli.
